This paper describes a 12.5 Gbps voltage mode transmitter with a high speed signal conditioning capability. Using a linear equalizer that is followed by a power efficient output stage, the transmitter achieves pre-emphasis at very low power consumption. In measurements, the transmitter can reliably transmit a 12.5 Gbps PRBS7 signal through a lossy 14 in. FR4 stripline commonly used in backplanes. It achieves a peak to peak jitter of 24 ps, a differential eye opening amplitude of 120 my, and a maximum common mode ripple of 40 mV. The proposed topology consumes 33 mW at-speed power which includes both the output stage and the linear equalizer. It also passes 8KV HBM ESD testing without compromising the high speed capability. The transmitter is fabricated in a 130 nm BiCMOS technology with 100 GHz maximum A and packaged in a commercial leadless leadframe package.
